What it is
An extract derived from the leaves and branches of Mentha arvensis, also known as cornmint or field mint. It is rich in menthol and other volatile compounds that give it a characteristic minty aroma and cooling effect.
How it works
When applied to the skin, the menthol in cornmint extract activates cold-sensitive receptors (TRPM8), creating a cooling sensation. This can temporarily soothe minor discomfort and reduce the perception of irritation. It also has mild antimicrobial properties that may help with surface bacteria.
Pros
Natural cooling effect
The menthol in cornmint extract provides a pleasant, refreshing coolness that can feel invigorating on warm days or after exercise.
Mild soothing potential
For non-sensitive skin types, it may help calm minor redness or irritation, making it a nice addition to soothing formulas.
Cons and cautions
Irritation risk for sensitive skin
Menthol can be a strong irritant for those with sensitive or reactive skin, leading to stinging, redness, or a burning sensation.
Not suitable for damaged skin
If your skin barrier is compromised (e.g., sunburn, cuts, or active breakouts), this extract can worsen irritation and delay healing.
Best for
- People who enjoy a cooling, tingly sensation in their skincare
- Those with normal to oily skin looking for a refreshing toner
Use caution if
- Individuals with sensitive, rosacea-prone, or eczema-prone skin
- Anyone with broken or irritated skin (e.g., after shaving or sunburn)
Usage tips
Safety summary
